UK scientists look to develop zero-emissions cement

18 July 2022, Published under Cement News

Scientists at the University of Cambridge, UK, have been replacing lime flux with used cement paste for steel recycling.   The resulting slag could, in turn, create a zero-emissions cement in a closed-loop process. ‘If the electric arc furnace [for steel recycling] is powered by non-emitting electricity, the only significant emissions in today’s steel recycling come from making the lime flux. So, with our process, it looks like we can make zero-emissions steel and zero-emissions ceme...
